Description

The dita test FO/xep step (FO_xep-none.xml is simplest) extracted from tests/john/dita/ATests is failing. Used the command:

-xsl:../DITA-OT1.8.5/plugins/org.dita.pdf2.SAXON/xsl/fo/topic2fo_shell_xep.xsl -s:stage1a.xml -t  -xsltversion:3.0 -diag:none/stats.xml -o:none/out.xml

fails during compilation with the following stack trace:
